OK if house trained
If rats can be house trained and a small team able to make and bring a cup of tea then cheaper on upkeep than monkey butlers.
Now if the implanted ones can also persuade the rest to visit the National Institute of Mental Health we may solve finally the rodent problem. Of course it's Asia they are more a problem eating up to 1/3rd rice crop. Maybe the Asians need more snakes rather than Robo-Rats.
